The court expanded their liability significantly.
Em um momento em que democracias ao redor do mundo buscam equilibrar liberdade de expressão e responsabilidade digital, o Supremo Tribunal Federal do Brasil avança para uma decisão histórica sobre a governança das plataformas tecnológicas. Por maioria, os ministros concederam sessenta dias para que as empresas implementem novas obrigações de moderação de conteúdo — um prazo que reconhece a complexidade técnica do desafio sem abrir mão da urgência moral. A questão central permanece antiga e universal: quando o dano se espalha por uma rede, quem deve responder por ele?
- O STF formou maioria para exigir que plataformas digitais adotem sistemas ativos de prevenção à circulação em massa de crimes graves, como terrorismo, exploração infantil e incitação ao suicídio.
- A tensão entre responsabilização e censura divide o tribunal: o ministro André Mendonça alertou que regras rígidas podem levar empresas a deletar conteúdo em excesso, sufocando discursos legítimos.
- O prazo de sessenta dias é uma concessão à realidade técnica — as empresas alegaram que conformidade imediata seria impossível, e o tribunal recuou do cumprimento instantâneo exigido anteriormente.
- Permanece em aberto se as obrigações valem apenas para plataformas com mais de um milhão de usuários no Brasil ou para todos os provedores que operam no país — uma distinção que define o alcance real da decisão.
- A proclamação oficial está marcada para 17 de junho, quando o Brasil terá um novo marco legal para a responsabilidade das plataformas, mas os embates sobre sua aplicação prática já estão anunciados.
O Supremo Tribunal Federal brasileiro se aproxima de uma decisão que redefinirá as obrigações legais das grandes empresas de tecnologia no país. Na quarta-feira, 17 de junho, o tribunal anunciará formalmente o resultado de um julgamento que consumiu meses de deliberação e que promete alterar profundamente a relação entre plataformas digitais e o Estado.
A questão de fundo é conhecida, mas sua solução é disputada: quem responde quando conteúdo criminoso se alastra por uma rede social? O direito brasileiro exigia, por anos, uma ordem judicial antes que as empresas fossem obrigadas a remover publicações. Isso mudou em junho do ano passado, quando o STF ampliou a responsabilidade das plataformas, determinando que a notificação de um usuário já seria suficiente para acionar o dever de remoção. Agora, o tribunal debatia quanto tempo as empresas teriam para se adaptar.
A maioria dos ministros convergiu para sessenta dias, contados a partir da publicação do acórdão. O prazo representa um recuo em relação à exigência de cumprimento imediato — reconhece a complexidade técnica sem abandonar a pressão sobre as empresas. As obrigações são amplas: as plataformas deverão adotar um "dever de cuidado" para impedir a circulação massiva de crimes graves, criar sistemas de autorregulação com relatórios anuais de transparência e estabelecer canais diretos de denúncia para usuários e não usuários.
O tribunal, porém, permanece dividido em pontos sensíveis. O ministro Flávio Dino defendeu que processos ajuizados antes da decisão de junho de 2025 sejam julgados pelas regras antigas, enquanto o relator Dias Toffoli propôs que casos em curso sigam o novo padrão — uma divergência sobre a retroatividade das obrigações. Já o ministro André Mendonça votou contra a expansão da responsabilidade, temendo que ela incentive a remoção indiscriminada de conteúdo e prejudique a liberdade de expressão.
Uma dúvida ainda paira sobre o alcance da decisão: as novas regras se aplicam apenas a plataformas com mais de um milhão de usuários cadastrados no Brasil, ou a todos os serviços que operam no país? A resposta determinará se o marco regulatório mira os gigantes ou abrange o ecossistema digital como um todo. Quando o tribunal falar na quarta-feira, o Brasil terá um novo ponto de partida — mas o verdadeiro teste virá quando as empresas começarem a implementar as regras e os primeiros conflitos chegarem aos tribunais.
Brazil's Supreme Court has moved closer to a landmark decision on how technology companies must police their platforms. On Wednesday, June 17th, the court will formally announce the results of a case that has consumed months of deliberation—a ruling that will reshape the legal obligations of social media giants operating in the country.
The core issue is straightforward in principle but thorny in practice: who bears responsibility when criminal content spreads across a platform? For years, Brazilian law required a judge's order before companies had to remove posts. That changed last June when the Supreme Court expanded platform liability, deciding that companies must act once a user flags illegal material—no court order necessary. Now the court is wrestling with how much time these companies should have to comply.
A majority of the justices have settled on sixty days. The clock starts when the court's written decision is published, giving platforms two months to build the systems and processes needed to meet their new obligations. This represents a compromise. The original ruling demanded immediate compliance, which the companies argued was technically impossible. The sixty-day window acknowledges that reality while keeping pressure on the platforms to act.
The obligations themselves are substantial. Companies must implement what the court calls a "duty of care"—actively working to prevent the mass circulation of serious crimes: terrorism, incitement to suicide, sexual abuse, child exploitation material. They must also create self-regulatory systems that publish annual transparency reports detailing how many posts were removed, which ads were promoted, and which content was amplified. And they must establish dedicated channels where both users and non-users can report problems directly to the company.
But the court remains divided on crucial details. Justice Flávio Dino broke ranks on one point: he believes that lawsuits filed before the June 26th, 2025 ruling should be judged under the old rules, even if they're still pending. The relator, Justice Dias Toffoli, proposed something different—that ongoing cases should follow the new standard, even if the harmful content was posted before the ruling existed. Dino saw this as creating duties retroactively, which he opposed. Justice André Mendonça went further, voting against the entire expansion of platform liability. He warned that the new rules would push companies to delete content aggressively, chilling legitimate speech. He lost that vote but succeeded in pushing back on other fronts.
Another unresolved question hangs over everything: do these obligations apply only to massive platforms with more than a million registered users in Brazil, or to every social media service operating in the country? The answer will determine whether this is a rule for the giants or a rule for everyone.
What emerges from the court's deliberations is a system caught between two competing pressures. One side wants platforms held accountable for the harm that spreads through their networks. The other worries that strict liability will simply lead to mass deletion and the suppression of speech that isn't actually illegal. The sixty-day deadline is a practical answer to a legal question, but it doesn't resolve the deeper tension. When the court announces its decision on Wednesday, Brazil will have a new framework for platform responsibility—but the real test will come when companies begin to implement it, and when users and courts begin to challenge how they do.
Notable Quotes
Before 2025, there was no duty of care. The proposed modulation would create duties retroactively.— Justice Flávio Dino, on the temporal scope of the ruling
We are generating an inhibitory effect because platforms, with reason, will delete content to protect themselves.— Justice André Mendonça, on the risk of over-moderation
The Hearth Conversation Another angle on the story
Why did the court feel it needed to give sixty days instead of enforcing immediate compliance?
Because the companies made a credible argument that you can't build detection systems and reporting infrastructure overnight. The court wanted accountability, but it also had to live in the real world.
So this is a win for the platforms?
It's a partial win. They got time to prepare. But they lost the bigger fight—the court expanded their liability significantly. Now they have to act on user reports without waiting for a judge.
What's the disagreement between Toffoli and Dino really about?
Whether the new rules should reach backward and affect cases that were already in progress when the ruling came down. Dino thinks that's unfair; Toffoli thinks ongoing cases should follow the new standard.
And Mendonça's concern about over-deletion—is that realistic?
Yes. If you're a platform and you're now liable for missing illegal content, you have an incentive to be aggressive. Better to delete something borderline than risk a lawsuit. That chills speech.
So the court knows this creates a problem but voted for it anyway?
The majority decided the harm from illegal content spreading unchecked outweighed the risk of over-moderation. Mendonça disagreed, but he was outvoted.
What happens if a platform just ignores the sixty days?
That's the next battle. The court will have issued an order. Defying it means contempt. But enforcement against a multinational company is complicated.
